URL Encoder/Decoder

Paste text or URL strings to encode/decode instantly, with optional safe-character mode.

Report

Plain Text / Original Input

Encoded URL Output

Tip: for query strings, enable “+ as space” to match common form-style decoding.

Type or paste

Enter text on the left to make it URL-safe, or paste encoded text on the right.

Live conversion & modes

Left input encodes to the right; right input decodes to the left. Switch between full encoding and keeping common URL characters.

Copy or swap

Use the toolbar to copy plain or encoded output, or swap both sides to keep editing.

If your data behaves like HTML form submissions, turn on “Treat + as space when decoding” for more predictable results.

When do I need URL encoding or decoding?

Whenever you put non-ASCII text or symbols in query parameters, or turn percent-encoded strings back into readable text—common in APIs, sharing links, and debugging.

Why can’t I put Chinese or special symbols directly in a URL?

URLs only allow a limited set of characters. Everything else should become percent-encoding so servers and browsers interpret the link the same way.

What’s the difference between full encoding and keeping URL-safe characters?

Full encoding is stricter and fits encoded parameter values. Safe mode leaves more punctuation unescaped so paths stay closer to what you typed.

Should “+” mean a space when decoding?

Form-style data often uses + for spaces; many plain URLs use %20 instead. Toggle the option to match where your string came from.

Why does it say the format is wrong?

Usually a % isn’t followed by exactly two hex digits, or the string was copied incompletely. Check for a lone % or truncated sequences.

Base64 isn't just "something that makes data longer." Every email with an attachment, every JWT token you receive after logging in, every tiny icon embedded in CSS — almost all of them use Base64. Here's why Base64 is everywhere, and what role it actually plays in modern systems.
